Title: Pulse-width fixing device
Inventor: IIDA TAKAHIDE
IPC: G01B9/02
Filed: 1991-04-24
Abstract: PURPOSE:To achieve counting even if a pulse-width reduction is equal to or less than a limit of a CPU by confirming pulse width by frequency-dividing a clock signal with a specified cycle and then controlling starting of an operation for confirming the pulse width corresponding to an input of fine time pulse. CONSTITUTION:A direction-discrimination input signal Aphiin or Bphiin is supplied to a terminal CK of D-FF1 or D-FF2. A reference clock signal phiin which is supplied from a CPU to a terminal Te is divided by two with FF1, is divided by four with FF2, and then is supplied to an NAND circuit. A pulse width to be fixed is determined by the FF1 and FF2. The FF2 is cleared by an AND circuit output, thus enabling direction-discrimination output signals Aphiout and Bphiout which are determined by a reference clock number of Th1=Th2=... to be output to terminals Tc and Td for allowing the FF2 to clear the D-FF1 and D-FF2 for intervals Th1, Th2... of a specified pulse width with the direction- discrimination input signal as a trigger. The frequency-divided value is selected so that counter of the CPU fixes the pulse width's Th1=Th2=... within a readable width consistently.

Title: Current variable circuit
Inventor: OIKAWA NAOHITO
IPC: H03F3/343
Filed: 1990-04-10
Abstract: PURPOSE:To vary a current supplied from an input terminal of a current mirror circuit by connecting in parallel FETs whose length is the same as width of a gate to an output side of the current mirror circuit. CONSTITUTION:A current mirror is constituted of MOSFETs Q2-Q5 whose gate electrodes are common to Q1, and as carrier mobility mu, oxide film thickness COX under the gate electrode, channel width W, length L, a gate - source voltage VGS, and a threshold voltage VTH, a drain current derived by an expression flows. An output current value becomes the product of the ratio of the number of FET for constituting a diode bias to the number of FET for constituting a current drawing-in part and a current value of an input constant-current source connected to an input terminal 1. For instance, it becomes 3/2Iref at the time of a current value Iref of a constant-current source which is connected to the terminal 1 and flows in. In such a way, by selecting arbitrarily the number of FETs for constituting the current mirror, the output current value can be varied variously against the input constant-current.

Title: Manufacture of thin film thermal sensitive head
Inventor: HARA HIDEKAZU
IPC: B41J2/335
Filed: 1987-04-20
Abstract: PURPOSE:To prevent the lowering in yield, by a method wherein a glaze built-up part is formed by a thick film production process in the same way as that for a partial glaze and thereafter, a thin film production process is started. CONSTITUTION:A partial glaze 2 and a glaze built-up part 3 are formed on a ceramic substrate 1 by printing glass paste to be baked. In that case, though it is necessary that the glaze built-up part 3 is made higher than the partial glaze 2, they are formed by making a printing number of times of the glaze built-up part 3 more than that of the partial glaze 2. Thereafter, a thermal resistor 4, and a conductor 5 are formed by sputtering. Then, they are coated by photo resist 6, and exposure is carried out by photomask 7. Then, develop ment and etching are executed, and a pattern is formed. Since the height of the glaze built-up part 3 is made higher than that of the partial glaze 2, the photomask 7 is in contact with the glaze built-up part 3, and does not contact with the partial glaze 2. Since the partial glaze and the glaze built-up part are formed in this way before the thin film production process, the yield deterio ration can be prevented.
